RAILW'AY-BOX-CAR CARLINE.

Application filed February My invent-ion relates to the roofing structure of box freight cars or in some instances to passenger cars also, the carline being, as it were, the beam which extends across the car from eave to eave and supports the roof structure.

The object of my invention is to furnish a very light cheap and strong carline using material that is of standard character, here shown as an I-beam section and to form the ends and body of the carline and supply it with the. necessary fittings which make it suitable in an efficient manner for the purposes intended and at the same time be acheaply constructed carline. In the accompanyingdrawings Fig. 1 is a transverse elevation of my carline showing the same as it extends from cave to cave of the car.

Fig. 2 is a plan of what is shown in Fig. 1.

Fig. 3 is a detail of the end of an Lbeam showing a preparatory step in the formation of my carline.

Fig. 4 is a detail view showing a cross section of a. sideplate of the car with my carline connected thereto.

Fig. 5 shows a detail step in forming the shoulder or brace piece which is attached to each end of the carline.

Fig. 6 is a transverse sectional elevation showing a further step in fastening of the brace piece to the body of the carline.

Fig. 7 is a transverse sectional elevation on line 7-7 of Fig. 4.

Fig. 8 is a plan View of what is shown in. Fig. 4.

Fig. 9 is a vertical transverse section of a form of fastening for the ridge/pole at the apex of the carline.

In making my carline I use the I-beam section of the standard form or any suitable form as indicated by 2. This car-line is bent into the form of an arch or other suitable form to provide for the water shedding incline for the. roof but I prefer to use an arch construction as then there is no serious bending in any one place required to form a straight rolled I-beam for the desired shape for the water shedding surface of the roof. One of the steps in furnishing a. commercial Lbeam into my carline is to shape each end as shown in Fig. 3 allowing the top flange 3 to extend, out as it were, and cut loose from the web 4 of the I-beam and cutting the lower flange of the Lbeam short as indicated by 5 and shaping the web end in the curved line a, 1926. Serial it. seen.

6 thus, see Fig. 3. .After the end of the carline is thus cut out the upper flange 3 is curved down and terminates at 7 as indicated by Fig. 4 leaving the coldshut line withthe web corresponding to the curve 6 of the web 4 of the I-beam. The purpose of curving down the flange 3 is to provide for fastening the roof sheets down over the cave of the cal and thus cover up asit were, the spaces on each side of the. web of the I-beam which is within the outer edges of the flanges .of'the I-beam. i

The common structure recently employed in boxcars is to provide what are called the sideplate in the form of Z-bars having a downward extending projecting flange 8 and a horizontal web 9 which forms a part of the water. shedding surface of the car body and with the upward projecting flange 10 to which the car line and roof are secured. In some forms of a roof there is provided an angle 11 riveted to the vertical leg 10 of the Z-bar sideplate.

For a suitable connection of my car-line with the sideplate I provide an angle or knee brace piece having end brace flanges 12 and with vertical web 13 riveted by rivets 21 to the sideplate and, with an inclined web 14 secured by rivets 15 to the lower flange 16 of my I-beam 2.

In addition toriveting brace pieces to the lower flange 16 of the I-beain I provide a sup plemental fastening in the form of projec tions of the metal of the brace pieces extend ing up through apertures in the lower flange 16 of the I-beam 2. These projections are formed as indicated by Fig. 5 by cutting a metal slit 17 in the body of the web portion 14 and then cut-ting loose and bending up points 18 into. vertical positions as shown by 19 in Fig. 6 and these projections are riveted or turned off as indicated by 20 in Fig. 7. Thus the projections 19 form additional rivets, as it were, to hold the web 14 to the lower flange 16 of the I-beam 2 and since these projections pass through apertures in the I-boani they make a very secure fastening altogether of the parts.

As an additional fastening for the carliue I provide a rivet passing through one side of the lower flange of the I-beam and secured to the angle 11. However, to facilitate the riveting of the rivet 22 I cut out a little notch 23 in the curve over the end of the upper flange of the I-beam 2, see Fig. 2.

The saddle for the ridgepole is mounted on top at the center of the carline and is held in place by bolts which pass through holes 24 in the flanges of the I-beam 2 and these holes are spaced apartlengthwise along the ca-rlines so that the carline flanges are weakened to an amount of one belt which bolt is fastened to the under side of the carline by means of bolts 25 which pass through holes through the lower flange only of the I-beam.

hen desired I fasten the ridgepole to the carline by means of secondary angle flanges 26 secured by rivets 27 through the web of the I-bealn and thus make unnecessary the holes 25 in the lower flange of the I-beam.

The modification shown in Fig. 9 has certain advantages over the alternate form of ridgepole fastening shown in Figs. 1 and 2; namely the rivet holes in the web of the carline pass through the neutral axis where they do not appreciably weaken the carline, whereas the piercing of the lower flange weakens it, and riveting through the web is preferable to riveting through the lower flange.

A like fastening for the purlins may be used in, the same manner as those for the ridgepoles.

I have disclosed novel features in this application which are also disclosed in my copending applications Ser. Nos. 88,229 and 96,529, and I expressly reserve the right to claim any novelty disclosed, but not claimed, herein in another co-pending application.

\"Vhat- I claim is:

1. A carline of I-heam section with its web vertically arranged and having; end portions of the lower flange and the web cut awa. leavin the u 3 361 marpin downwardl CUrYGd, the upper flange extending beyond the lower flange and curved downwardly over said curved margin.

2-. A carline formed from a rolled section having end portions of the lower flange and web cut away leaving the upper web margin downwardly curved with the upper flange initially extending; beyond the lower flange then bent downwardly over said curved margin.

Signed at Chicago, in the county of Cook and State of Illinois this 5th day of February, 1926.
